ClearCase’s sole purpose is to make my life difficult. The company could save vast amounts of money by using cvs/subversion/etc and employing an unskilled worker to kick me repeatedly in the balls. They’d get the same effect, with the adding bonus of occasionally developing some software.
I have days like that. Not specifically about ClearCase (we use Subversion for all the projects that I can’t get out of Visual SourceSafe), but it’s not the only commercial product that makes you feel like that.
